What modules to understand first ?

[Abhishek K Das]

Hello everyone !

I am a newbie here . Please forgive me , if you find this question lame . As I asked a few days ago , that how can I contribute to sympy
and Aaron replied by giving the links to easy-to-fix issue list and the development work-flow .
Now what I am asking is that to write good code for issues or developing new stuff , one needs to understand all the **core classes and modules**
ie how the things have been implemented internally , without the knowledge of that it is a bit difficult to straight away write code for patches/issues .

I will make my question clear and straight . So my question is that which all modules are **essentially important** for one to get hold off , so that
one can understand the main things working under the hood . I mean it would be very nice if one could pin-point the exact files/modules which one needs
to understand to get a head-start in writing good code .

Thanks in advance .

That page is actually quite old (I am trying to remove it
https://github.com/sympy/sympy/pull/2807).

My advice is that the core is the worst place to start if you are
trying to understand the code in SymPy. It is by far the hardest to
understand. I would start with one of the high-level modules that
interested you (solvers, simplify, stats, sets, etc.), and only once
you understand how to use SymPy in a high-level way, then start to try
to understand how the core works.

The best place to start is with the tutorial, as that will show you
how to use SymPy as a user. Since SymPy uses itself, this is important
even if you wish to develop on SymPy.
